This invention relates to lasts over which shoes the outsole being shown partly broken away, are shaped and built up, particularly to lasts for Fig. 'l' is a part side elevation and part vertical use with the process shown and claimed in my longitudinal section through the finished shoe; copending application Serial No. '750,763 filed and October 3l, 1934, now Patent No. 2,090,019, dated Figs. 8, 9 and l0 are views similar to Figs. 3, 4 10 August 17, 1937, for making shoes without an and 5, respectively, showing a last for use in a l0 insole in the forepart thereof. different process.

The outsole E. is then cemented upper pulled over and secured to the shank piece or otherwise secured to the lasted margin of the and to the marginal portion of the forepart of the upper, after which the last, together with the forelast, part protecting member B thereof, are withdrawn Fig. 3 is a vertical cross-section on the line 3 3 from the shoe. 50 of Fig. 2, The last used with the process illustrated in Fig. 4 is a View similar to Fig. 3, showing the Figs. 8, 9 and 10 is provided with a protecting lasting tacks removed and the excess lasting member or plate B whose underside is rabbeted, allowance of the upper cut away, as at t, around its sides and toe portion to ac- Fig. 5 is a view similar to Fig. 4, showing the commodate the inner marginal portion of a last- 55 ing tape F whose outer margin is turned up beyond the edge of the last protecting member to form an upstanding lasting lip 1. As shown in Figs. 8, 9 and V10, the lasting tape F may be cemented or otherwise secured, as at 8, to the rabbeted marginal portion 6 of the protecting plate it may also be clamped between the plate and the last; or it may be cemented or otherwise secured to the last. In making shoes with this form of last protecting member, the upper is pulled over the last with its marginal portion or lasting allowance secured by cement 8 to the exposed margin of the last and by staples 9 to the outer side of the upstanding lip 1 of the lasting tape F. After the cement 8 has set sufficiently to hold an upper to the exposed margin of the last, the lip 1 of the lasting tape and the lasted portion of the upper cooperating therewith are cut away, as shown in Fig. 9, and carry with them the staples 9 used to secure them together. The lasted margin of the upper is then feathered or beveled in the manner hereinbefore described, after which the outsole is laid and the last, together with the protecting member F and the remaining portion of the lasting tape, are Withdrawn from the shoe.

By the arrangement described, the surface of the last is protected against damage by the feathering or beveling tool, thereby prolonging the life of the last, and the protecting member may be used as a means for holding the lasting tape in position on the last or the lasting lip may be formed integral with the protecting member.

Obviously, the hereinbefore described invention admits of considerable modification Without departing from the invention. Therefore, I do not wish to be limited to the precise construction shown and described.

Reference is hereby made to my copending application Serial No. 85,641 filed June 17, 1936, now Patent No. 2,081,887 dated May 25, 1937, for the shoe making process described but not claimed herein.

What I claim is:

1. A member for protecting the bottom of the forepart of a last during the operation of feathering the margin of the forepart of an upper lasted directly to the margin of the last bottom, said member being shaped and arranged to cover the portion of said last bottom not covered by the feathered lasted margin of the upper, the underside of the marginal portion of said member being rabbeted to receive the last engaging margin of a lasting strip.

2. A member for protecting the bottom of the forepart of a last during the operation of feathering the margin of the forepart of an upper lasted directly to the margin of the last bottom, said member being shaped to cover the portion of said last bottom not covered by the feathered lasted margin of the upper, the marginal portion of said member being beveled to conform substantially to the peripheral cutting edge of a rotary feathering tool, said member being shaped and arranged to cover the portion of said last bottom not covered by the feathered lasted margin of the upper, the underside of the marginal portion of said member being rabbeted to receive the last engaging margin of a lasting strip.
